Syllabus

<p>1. Patents — Infringement—Incandescent Lamp Sockets.</p> <p>The Perkins patent, No. 626,927, for an incandescent lamp socket, was not anticipated, and. while the parts were old, covers a new combination of utility, and discloses patentable invention. Claims 3, 4, and 9 also held infringed. '</p> <p>2. Same — Combination and Aggregation Distinguished.</p> <p>Elements of the patent considered, and held to constitute, not a mere aggregation of separate elements, but a composite construction, in which the several parts co-operate to produce a common and combined result, which the law accepts and sustains.</p>
